Maybe something like the Dendrobium from 0083. Not so much a support structure since it's space use, but it is a mobile suit surrounded by a full on weapons system.
There might be something like that in the Advance of Zeta stuff given how it has a bunch of modular systems, but I'm not that well versed in it to know for certain. 99% of the kits are also P bandai if they happen to exist.
